During pregnancy, the body will produce some osteoporosis hormones, which mainly allow the pelvis to slowly open in preparation for childbirth. If the fetus is larger and the delivery is vaginal, severe pubic separation is more likely to occur. I am from Yulin. My second baby was 8 pounds, and I also had this problem. It was not relieved 3 months after giving birth. I went to Yuen to have my pelvis repaired.
